I was more thinking about the higher layers. Here it's simpler to setup alist of pages which can be send to a lower layer. In the page cache wealready have per address space lists, so it would be very easy to usethat. A lower layer can generate of course anything it wants out of this,e.g. it can generate sublists or vectors.
